FIELD OF THE INVENTION

The present invention relates to hydrometeorology, in particular, activemethods and devices for acting on atmospheric formations and theircontrolling, hail alerting and prevention, and may be used for automaticrealization of anti-hail protection of agricultural fields, orchards,vegetable gardens and various public and social objects.

BACKGROUND

Several methods of wide-ranging (large-scale) anti-hail protection areknown in the art. It is known a wide-ranging anti-hail protection methodwith an active effect (impact) on hail clouds by shells or rockets whichspread reagents or aerosol in clouds.

It is known as well an anti-hail protection method with (including) anactive effect (impact) on hail clouds by significant (powerful) shockwaves directed upwardly to the sky. It is believed that the successionof shock waves transports positive ions from ground level to cloud levelwhich disrupt formation of hail nuclei. Wide-ranging application of thismethod of anti-hail protection is fulfilled by the following way.Supersonic and significant shock waves are generated and are directedupwardly to the sky in any (each, every) site of an anti-hail protected(protection) area of M sites by sequential (serial) detonating anexplosive mixture of combustible gas (combustible fuel) and air in acombustion chamber (in an enclosed body) of any (each, every) of M hailpreventing sonic generators (an anti-hail shock wave generators) arespatially distributed (positioned, are placed) in M sites (points) ofthe anti-hail protected area of M sites. By selecting material andquantity of the combustible fuel, number and duration of detonations itis possible to provide significant shock waves and to effect on the hailclouds up to 10 km of altitude, changing hail cloud structure,preventing further development of hail and transforming hail to (into)rain, to wet snow or to small ice drops. As the fuel or combustible gasmay be used acetylene gas, a mixture of propane-butane gases or othergas or liquid fuel with high energy capabilities. The explosive mixtureof injected into the combustion chamber combustible gas and air isdetonated by an inside located igniter in accordance with externalcommand signals incoming from a controller (a control means). Thesecommand signals are created in the controller by an assisting (service)operator (staff) manually or remotely by means of cell phone GSM system,by radio aids (by radio technical devices), by means of radiocommunication, by means of telephone communication, or by othertechnical means of communication.

It is known as well an anti-hail protection method using shock waveswhen simultaneously with the injecting of the combustible gas a reagent(argentum iodide, for instance) is injected into the combustion chamberand is mixed with the explosive mixture of combustible gas and air.Coming up small particles of the burned reagent immediately (directly)effect on the process of hail forming in addition to the shock wavesimpact.

Known anti-hail protection methods have some limitations (disadvantages)related to the absence of automatic operation and self-management(self-controlling) capabilities. Known anti-hail protection methods areoperated only when corresponding commands come from the assisting(service) operator (staff), which includes subjective factor, or whencorresponding commands came from an anti-hail radar station (weatherradar station) which is a very expensive one and needs specific(special) exploitation conditions, besides it is not always possible toget (to receive) the commands from the anti-hail radar station, or thesecommands are not always contained (included) correct (real) informationabout hail situation and stage regarding the protected (considered orspecified) area. However, to achieve by shock waves successful and goodresults in wide-ranging anti-hail protection it is necessary in thegiven (specified) site of shock wave generator's impact area (typicallya 500-600 m radius) to start detonations automatically, without thehuman action, at least 5-10 minute prior (before) a hail storm.

Current method of wide-ranging application (utilization) of shock wavemethod, which is more fit (match) to the present invention, comprisesgeneration supersonic and significant shock waves in any (each, every)site of the anti-hail protected area of M sites by sequential (serial)detonating an explosive mixture of preliminary injected combustible gas(combustible fuel) and air in a combustion chamber (in an enclosed body)of the hail preventing sonic generator of that site (corresponding site)and direction the shock waves upwardly to the sky, wherein thepreliminary injection (injecting) before each detonating of thecombustible gas into the combustion chamber and the detonating of theexplosive mixture of the preliminary injected combustible gas and air inthe combustion chamber by an inside located igniter are performed inaccordance with the command signals incoming from the controller(control means) of that site, wherein the external command signals arecreated by (in) the controller in accordance with the signals receivedfrom (transmitted by) a servant anti-hail radar station of that siteremotely by means of cell phone GSM system.

Current anti-hail protection method's disadvantage is its low operationefficiency due to the dearness (high price) of the automaticexploitation of wide-ranging anti-hail protection network, since theanti-hail radar station costs very expensive, and due to the absence ofself-management (self-controlling) capabilities.

Current wide-ranging anti-hail protection network which realizes inpractice the above mentioned anti-hail protection methods and which ismore fit to the present invention, includes M independently operatinghail preventing sonic generators (anti-hail shock wave generators)spatially distributed (positioned, are placed) in M sites of theanti-hail protected area of M sites, any one of M hail preventing sonicgenerators comprises a cylindrical combustion chamber having a neck withan upper orifice, a conical barrel, air inlet ports provided with flaps,a fuel supply system (fuel injection means), an ignition means and anigniter, a control means and a power supply.

Current wide-ranging anti-hail protection network's disadvantage is itslow operation efficiency due to the dearness of the automaticexploitation of wide-ranging anti-hail protection network and theabsence of self-management (self-controlling) capabilities, since all Mspatially distributed in M sites of the anti-hail protected area of Msites hail preventing sonic generators are controlled by one controllingcenter, by the anti-hail radar station which costs very expensive, needsspecific (special) exploitation conditions and is very power consumingone.

An object of the present invention is to enhance operation efficiency ofthe wide-ranging anti-hail protection network and to automate itsexploitation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows a possible outline of a location of an anti-hail protectionarea of M sites which is served by an automated wide-ranging anti-hailprotection network of M spatially distributed anti-hail protectionsystems (1).

The bottom of combustion chamber (19) is solidly mounted to aconcrete pad (21) by feet (22). One or more air inlet ports (23) areprovided with flaps (not shown) which are seated in ports (23) and openinwardly to provide one way valves for air rushing into combustionchamber (19) after each ignition. Combustion chamber (19) is providedwith a fuel injector (24) which may be located in (inside) or on thecombustion chamber (19) and which may comprise a solenoid valvecontrolling flow of combustible gas from a combustible fuel reservoir(25) of a fuel supply system (3) through a mechanical valve (26), asolenoid valve (27) and a pressure regulator (a pressure reducer) (28)into a central portion of combustion chamber (19). An igniter (29) whichmay comprise spark gap electrodes and an ignition means (4) which maycomprise a high voltage generator coil are provided for igniting thecombustible fuel injected into combustion chamber (19) and which may belocated outside (FIG. 2) or inside (FIG. 6 and FIG. 7) of combustionchamber (19). Solenoid valve (27), fuel injector (24) and ignition means(4) are controlled by control means (5). A conical barrel (30) has alarge diameter upper end (31) and a small diameter lower end (32) whichis connected to an upper orifice (33 a) in neck (20) of combustionchamber (19).

FIG. 4 shows the details of a possible embodiment of a controlled codecomparator (15) which includes L independent channels of comparison andan adder (Σ). Any one of L independent channels of comparison includes asubtracter (−), a squarer ([ ]²) and a reverse threshold circuit (0/1).

FIG. 5 shows possible values of maximum, minimum and alert thresholdslevels at various frequencies.

Preferred modes of operation of the system of FIG. 2 are now describedwith reference to FIG. 1-FIG. 5. After initial starting (running) of thewide-ranging anti-hail protection network, that is after initialstarting of any (each) of M anti-hail protection systems (1) of thewide-ranging anti-hail protection network, that is after openingcorresponding mechanical valve (26) of each (any) of anti-hailprotection system (1) and switching on corresponding power supply (6)which begins feed corresponding control means (5), correspondingignition means (4) and corresponding detector-warner (7), each (any)anti-hail protection system of the network and the whole of anti-hailprotection network continue their operation autonomous andautomatically. Control means (5) of any (each) anti-hail protectionsystem (1) opens corresponding solenoid valve (27) and setscorresponding hail preventing sonic generator (2) in a waiting mode ofoperation. Flow of the combustible gas through open correspondingsolenoid valve (27) and corresponding pressure regulator (pressurereducer) (28) comes to the input of closed fuel injector (24) ofcorresponding hail preventing sonic generator (2). Up-directed antenna(8) of corresponding anti-hail protection system (1) observes the sky,receives continually signals of sky proper radiothermal emission andtransfers them to the input of corresponding radiometric receiver (9).Radiometric receiver (9) processes received signals and outputs(transfers) to the input of corresponding controlled compensation device(circuit) (10) a signal corresponding to a sum of powers of signals ofexternal emissions (from sky, surrounding (ambient) and externalinterference) and internal noises. Controlled compensation device(circuit) (10) compensates (reduces) a part of the incoming signalscorresponding to clear air condition of sky observation and outputsremainder of the signals to the input of corresponding controlledmulti-channel thresholder (11). In controlled multi-channel thresholder(11) the remainder of the signals is compared with N various thresholdlevels in N single level thresholders (SLT). Each single levelthresholder (SLT) outputs “one” (“1”) signal to the corresponding inputof corresponding warning device (12) if its input signal exceeds therespective threshold, and a “zero” (naught, “0”) signal otherwise.Warning device (12) records (processes) jointly received “one” and“zero” signals as a binary number in a binary code, creates a binarynumber code-signal corresponding to the recorded binary number,generates a warning code-signal in accordance with the binary numbercode-signal and outputs (transfers) generated warning code-signal to theinput of corresponding transmitter (19) and to the input ofcorresponding control means (5) by electrical cords. Control means (5)sets the operation mode of corresponding hail preventing sonic generator(2) in accordance with the received warning code-signal, such as aswitching-on mode, a waiting mode, an operating mode and a turning-offmode, and sets operation parameters, such as power (the combustible fuelquantity) and duration of detonations, number (frequency) of detonationsand a detonation window. Control means (5) keeps corresponding hailpreventing sonic generator (2) in a waiting mode of operation ifreceived warning code-signal has the value “0”. When control means (5)receives a warning code-signal with the value “1” or more it sets theoperating mode of operation of corresponding hail preventing sonicgenerator (2), sets operation parameters of corresponding hailpreventing sonic generator (2) in accordance with the value of thereceived warning code-signal, generates (creates) command (control)signals and runs (triggers, activates, starts) corresponding hailpreventing sonic generator (2).

When hail preventing sonic generator (2) is operated, correspondingcontrol means (5) causes combustible fuel to be released throughcorresponding fuel injector (24) into corresponding combustion chamber(19) until sufficient combustible gas for a full explosion resulting ina significant shock wave is present in corresponding combustion chamber(19). Mixing of the combustible fuel (combustible gas) with air incombustion chamber (19) is automatic and rapid. A short time aftersolenoid valve of fuel injector (24) is closed corresponding controlmeans (5) triggers spark gap coil of corresponding ignition means (4) tocreate a high voltage pulse resulting in a spark across the electrodesof corresponding igniter (29). As the gas in combustion chamber (19)rapidly combusts, a shock wave results which is directed bycorresponding conical barrel (30). The momentum of the combustion gasesis directed upwardly, and once the combustion gases have fully expanded,the upward momentum of the gases causes a negative pressure to becreated in combustion chamber (19) which results in corresponding flapsof corresponding air inlet ports (23) being drawn open so that fresh airmay be drawn from ambient through air inlet ports (23) to fillcorresponding combustion chamber (19).

It is important to select a fuel and ignition system which can operateeven when rain water (ice, snow) passes through conical barrel (30) intocorresponding combustion chamber (19). It is important to select theparameters of combustible fuel, combustion chamber (19) volume tocorresponding upper orifice (33 a) size as well as corresponding conicalbarrel (30) dimensions in order that a good shock wave is generated andsufficient aspiration through corresponding air inlet ports (23) takesplace in order to bring in sufficient fresh air for the next combustion.

Simultaneously with setting the operating mode of operation of hailpreventing sonic generator (2) corresponding transmitter (13) generatesand transmits on the air an alert code-signal.

When control means (5) receives the warning code-signal corresponding tothe upper-range (maximum) value of the binary number

$P = {\sum\limits_{k = 1}^{N}2^{k - 1}}$results when “one” signal is transferred to any (each) of k=1÷N inputsof corresponding warning device (12) the control means (5) sets theturning-off mode of operation of corresponding anti-hail protectionsystem (1), switches off corresponding hail preventing sonic generator(2) and interrupts detonations that is stops fuel injection andignition. Control means (5) switches on corresponding hail preventingsonic generator (2) and resets for corresponding hail preventing sonicgenerator (2) the waiting mode of operation when it receives fromcorresponding warning device (12) next (next in turn) signal with thevalue “0” only.

The number N is defined on the basis of technical capabilities andperformance to change operation parameters of corresponding hailpreventing sonic generator (2), such as power and number of detonations,repetition frequency of detonations or a detonation window.

After initial starting of any (each) of M anti-hail protection systems(1) of the wide-ranging anti-hail protection network and simultaneouslywith setting the waiting mode of operation of any (each) of M hailpreventing sonic generators (2) of the anti-hail protection networkcorresponding receiver (14) begins listening watch (ether) for receptionalert code-signals transmitted on the air from other sites of theanti-hail protected area of M sites. Controlled code comparator (15) ofcorresponding receiver (14) compares outputs of corresponding receiver(14) with L proper code-signals of the corresponding site and generatesan alert signal if received alert code-signal coincides with any of Lproper code-signals of the corresponding site, and a “zero” (naught,“0”) signal otherwise. Output signals of controlled code comparator (15)come to the controlled terminal (input) of corresponding firstcontrolled switcher (16) which joins (connects, links) togetherinput/output terminals of corresponding first controlled switcher (16)if an alert signal comes to the controlled terminal of correspondingfirst controlled switcher (16), and keeps disjoined (disconnected)input/output terminals of corresponding first controlled switcher (16)otherwise. First controlled switcher (16) with joined input/outputterminals connects an output of corresponding controlled compensationdevice (circuit) (10) with an input of corresponding controlledsingle-channel thresholder (17), single-channel thresholder (17)compares accumulated signals of the corresponding site with an alertthreshold and an alerting code-signal is generated and is outputted (istransferred) to the corresponding output of single-channel thresholder(17) if corresponding accumulated signal exceeds the alert threshold,and a “zero” (naught, “0”) signal otherwise. The alerting code-signalpasses (goes) through second controlled switcher (18) with joinedinput/output terminals and from the output terminal of second controlledswitcher (18) is transferred by (through, via) electrical cords to thecorresponding input of corresponding control means (5) which generatesan alert command (control) signal and starts up corresponding hailpreventing sonic generator (2) in accordance with generated alertcommand signal at (by, under) specified operational conditions of analert operating mode of operation of hail preventing sonic generator(2). The alert operating mode of any hail preventing sonic generator (2)of any site of the anti-hail protected area of M sites is turned-off(switched-off) simultaneously with interrupting the alert code-signalcorresponding to that site, that is when a “zero” signal comes from theoutput of corresponding controlled code comparator (15) to thecontrolled terminal of corresponding first controlled switcher (16),when corresponding first controlled switcher (16) disjoins itsinput/output terminals and by that way disconnects the output ofcorresponding controlled compensation device (circuit) (10) from theinput of corresponding controlled single-channel thresholder (17). Thealert operating mode of operation of any hail preventing sonic generator(2) of any site of the anti-hail protected area of M sites is turned-off(switched-off) as well simultaneously with setting the operating mode orthe turning-off mode of operation of corresponding hail preventing sonicgenerator (2), when corresponding warning device (12) of that sitegenerates a warning code signal with a value “1” and more, up toupper-range (maximum) value

$P = {\sum\limits_{k = 1}^{N}2^{k - 1}}$results when “one” signal is transferred to any (each) of k=1÷N inputsof corresponding warning device (12), then (when) corresponding secondcontrolled switcher (18) disjoins (disconnects) its input/outputterminals due to non-zero code-signals at its controlled terminal(input) and by that way disconnects the output of correspondingcontrolled single-channel thresholder (17) from the corresponding inputof corresponding control means (5). This is a way to enhance operationefficiency of the wide-ranging anti-hail protection network and toautomate its exploitation.

Detector-warner (7) may be mounted at any distance (close, near, not sofar, far) away from corresponding hail preventing sonic generator (2)and, therefore, may have as well a separate power supply (33) as shownin FIG. 6.

If there is not a possibility to use electrical network ˜110V or ˜220Vas a basic electrical source for power supply (6) and for separate powersupply (33) then a preferred embodiment for both power supply (6) andseparate power supply (33) is 12V or 24V DC rechargeable solar batterywith a solar power panel.

Antenna (8) of any (each) of M anti-hail protection systems (1) may bedirected to the sky under any elevation (vertical) and azimuth angles.Preferable elevation angle is from the interval 0-30⁰ from the vertical.When detector-warner (7) is mounted close (near) to corresponding hailpreventing sonic generator (2) then more preferable interval forradiometric observation is 0-10⁰ from the vertical. Preferable azimuthdirection for radiometric observation is the sector NorthWest-North-North East, since it allows practically exclude the Sundirect influence on antenna at any time and at any season. Fordetector-warner (7) any kind of antenna may be used, e.g. horn, onemirror parabolic and hyperbolic, two mirrors (Cassegrainian) parabolic,dielectric, etc. with any beamwidth. Preferable antenna beamwidth is10-20⁰ at 3 dB level. Radiometric receiver (9) of any (each) of Manti-hail protection systems (1) may operate at any allowed centralradio frequency from L to W-band of microwave (L, S, C, X, Ku, K, Ka,W), at any interference (noise) free bandwidth of receiving (reception)and at any polarization of sensing. Preferable bands for operation areX, Ku, K and Ka bands. For detector-warner (7) any type radiometricreceiver may be used, such as a radiometer with a direct amplification,a superheterodyne radiometer, a noise-compensated (direct) radiometer, aDick radiometer, a correlation radiometer, a crystal (detector)radiometer, etc. For radiometric receiver (9) preferred integration timeis 1-5 second and preferred sensitivity is 0.1-0.5K in dependence onfrequency band.

Detector-warner (7) should be mounted or it is necessary to mountdetector-warner (7) under a convex radiolucent protective apron (shed,canopy, hovel) or/and to cover corresponding antenna (8) by radiolucentprotective layer to prevent ice and liquid accumulation in front ofcorresponding antenna (8) and to protect corresponding antenna (8) andcorresponding radiometric receiver (9) from direct influence of dust andprecipitation, e.g. rain, snow, hail, etc. If the protective apron isconstructed from a non-transparent or partially transparent material,then the apron should not cover (cut) the beam (the main lobe) ofcorresponding antenna (8).

Threshold levels of controlled multi-channel thresholder (11) depend onoperation frequency (frequency band) of corresponding radiometricreceiver (9). A curve of minimal threshold level's frequency dependenceof FIG. 5 corresponds to a radiothermal contrast's frequency dependenceof cumulonimbus clouds caused (generated) a rainfall with rare hailstones. Minimal values of radiothermal contrasts of FIG. 5 wereestimated and approximated from the results of multi-frequency and dualpolarization (vertical and horizontal) radiometric measurements carriedout under elevation angles 20⁰ and 30⁰ of sensing and from the knowntheory of passive (radiometric) remote sensing. Theoreticalapproximations show that these curves are acceptable for elevationangles from the interval 0-30⁰ as well.

Maximal threshold level's frequency dependence of FIG. 5 was estimatedand approximated from the results of theoretical and experimentalresearches and corresponds to a radiothermal contrast's frequencydependence of cumulonimbus clouds caused (generated) a hard hail stormwhich is impossible to prevent by any technical means.

Alert threshold level of controlled single-channel thresholder (17)depends on operation frequency (frequency band) of correspondingradiometric receiver (9) and in dependence on frequency band ofoperation of corresponding radiometric receiver (9) is about 3-15Ksmaller than corresponding minimal threshold level. Alert thresholdlevel's frequency dependence of FIG. 5 was estimated and approximatedfrom the results of theoretical and experimental researches.

Radiothermal contrasts of FIG. 5 are given in Kelvin. Correspondingthresholds values in volts depend on structure and technical parametersof used (utilized) radiometric receiver (9) and may be defined from theresults of theoretical estimations or from the results of experimentalmeasurements and calibration. A preferable solution is to carry outpreliminary calibration of radiometric receiver (9) in laboratoryconditions or to carry out calibration of detector-warner (7) in fieldconditions.

A threshold interval between maximal and minimal thresholds levels ofFIG. 5 may be divided in N−1 parts, where the dividing by 2 or 4 or 8 or16, etc. parts that is when N=3 or 5 or 9 or 17 etc. is preferable. Independence on application features (conditions) of the present methodand the network of wide-ranging anti-hail protection the values ofmaximal, minimal and alert thresholds levels of FIG. 5 may be changed.When the value of minimal and alert thresholds levels of FIG. 5 isdecreased then hail detection probability and false alarm are increasedsimultaneously. Taking into account a low exploitation expenditures (lowprice of combustible fuel) of hail preventing sonic generator (2), it ispossible to agree with high false alarm probability and to decreaseminimal and alert thresholds levels of FIG. 5 by 2-10K in dependence onoperation frequency of corresponding radiometric receiver (9).

It is possible to save material resources and to decrease exploitationexpenditures of hail preventing sonic generator (2) by decreasing thevalues of maximal threshold levels of FIG. 5 which will cause increasingof a target (hail storm) drop-out probability.

Maximal, minimal and alert thresholds levels may be corrected and may bechanged individually during the exploitation of corresponding anti-hailprotection system (1) by corresponding controlled multi-channelthresholder (12) and by corresponding controlled single-channelthresholder (17).

The hail preventing sonic generator's (2) impact area is limited in asize and usually is about 500-600 m in a radius over the generator.Therefore, the hail preventing sonic generator is mounted (is built)near protected agricultural fields and lands and is set in its waitingmode of operation after clarification of the value of a compensationsignal of controlled compensation device (circuit) (10). The value ofthe compensation signal for hail preventing sonic generator (2) workarea is defined experimentally for each protected area individually byaveraging the results of measurements of clear sky brightnesstemperatures (more exact antenna or apparent temperatures) carried outduring days and nights under (for, at) various ambient (near surface)air temperatures 10-30° C.

FIG. 6 shows second preferred embodiment of anti-hail protection system(1) with reagent injecting facilities in respect to the embodiment ofFIG. 2. For sake of conciseness, only the differences with respect tothe embodiment of FIG. 2 are discussed below. FIG. 6 shows in additionthe following high-level components and details thereof: a reagentsupply system (34), a reagent reservoir (35), a reagent mechanical valve(36), a reagent solenoid valve (37), a reagent pressure regulator (38)for providing required pressure for reagent injection, and a reagentinjector-mixer (38) for injecting a reagent together with thecombustible fuel into corresponding combustion chamber (19) and mixingthe reagent with the combustible fuel before the combustible fueldetonating. Reagent injector-mixer (38) which is controlled bycorresponding control means (5) may comprise a solenoid valvecontrolling flow of the reagent from corresponding reagent reservoir(35) of corresponding reagent supply system (34) through correspondingreagent mechanical valve (36), corresponding reagent solenoid valve (37)and corresponding reagent pressure regulator (38) into a central portionof corresponding combustion chamber (19). Reagent mechanical valve (36)is opened together with corresponding mechanical valve (26). Reagentinjector-mixer (39) is opened and is closed by corresponding controlmeans (5) simultaneously with corresponding fuel injector (24) or so.

When detector-warner (7) is mounted not so far (away) from correspondinghail preventing sonic generator (2) then it is preferable to transferthe warning code-signal generated (created) by corresponding warningdevice (12) and the alerting code-signal generated (created) bycorresponding controlled single-channel thresholder (17) tocorresponding control means (5) by (through, via) electrical cords. Whendetector-warner (7) is mounted far (away) from corresponding hailpreventing sonic generator (2) then it is preferable to control hailpreventing sonic generator (2) remotely and transfer the warningcode-signal generated by corresponding warning device (12) and thealerting code-signal generated by corresponding controlledsingle-channel thresholder (17) to corresponding control means (5) bymeans of cell phone GSM system, by radio aids (by radio technicaldevices), by means of radio communication, by means of telephonecommunication, or by other technical means of communication.

FIG. 7 gives an overview of third alternative preferred embodiment ofanti-hail protection system (1) which is controlled remotely. For sakeof conciseness, only the differences with respect to the embodiments ofFIG. 2 and FIG. 6 are discussed below. FIG. 7 shows in addition thefollowing high-level components and details thereof: a remote controlsystem (40), a controlling transmitter (a controlling transmittingphone) (41) for transmitting created warning and alerting code-signals,a controlling receiver (a controlling receiving phone) (42) forreceiving transmitted warning and alerting code-signals and transferringreceived warning and alerting code-signals by (through, via) electricalcords to corresponding control means (5).

When detector-warner (7) is located far (away) from corresponding hailpreventing sonic generator (2) its antenna (8) should be directed underthe elevation angle providing a footprint at ˜3.5 km altitude just abovecorresponding site of protected agricultural area.

An automate exploitation or a self-management (self-controlling) of thewide-ranging anti-hail protection network may be realized as well by ateledetection complex of K teledetection systems (43) which serves theanti-hail protected area of M sites as shown in FIG. 8. Theteledetection complex of K teledetection systems (43) is used forfar-ranging hail (hail clouds) detection over an adjacent land allaround the anti-hail protection area of M sites at a horizontal distance3-4 km far from the edge (boundary) of the anti-hail protection area ofM sites and at the altitude 3.5 km and for alerting by transmitting onthe air the alert code-signal on gathering (coming, impending) haildanger from a specified adjacent land of the anti-hail protection areaof M sites.

The number K depends on the kind (type) of a spatial distribution of Msites and it may have a value from the interval [1÷M], e.g. if M sitesare spatially distributed around a common center a possible embodimentof which is separately presented in FIG. 8, then it will be possible touse only one (K=1) teledetection system (43). If all M sites are locatedone far from another then for entire serving of the anti-hail protectionarea of M sites it will be necessary to use K=M teledetection systems(43).

Any one of K teledetection systems (43) comprises a far-ranging antenna(44) for receiving signals of the adjacent land corresponding sky properradio thermal emission, a far-ranging radiometric receiver (45) formeasuring a power of the received signals of the adjacent landcorresponding sky proper radio thermal emission and for estimating ofthe adjacent land corresponding sky brightness (apparent) temperature,far-ranging radiometric receiver (45) being in electrical communicationwith corresponding far-ranging antenna (44), a far-ranging controlledcompensation device (circuit) (46), far-ranging controlled compensationdevice (46) being in electrical communication with correspondingfar-ranging radiometric receiver (45), a far-ranging controlledsingle-channel thresholder (47) for far-ranging hail detection,far-ranging controlled single-channel thresholder (47) being inelectrical communication with corresponding far-ranging controlledcompensation device (46), a far-ranging warning device (48) for creationthe alert code-signal on gathering hail danger from the adjacent land,far-ranging warning device (48) being in electrical communication withcorresponding far-ranging controlled single-channel thresholder (47), afar-ranging transmitter (49) for transmitting on the air the alertcode-signal on gathering hail danger from the adjacent land, far-rangingtransmitter (49) being in electrical communication with correspondingfar-ranging warning device (48), and a far-ranging power supply (50),far-ranging power supply (50) being in electrical communication withcorresponding far-ranging radiometric receiver (45), with correspondingfar-ranging controlled compensation device (circuit) (46), withcorresponding far-ranging controlled single-channel thresholder (47),with corresponding far-ranging warning device (48) and withcorresponding far-ranging transmitter (49).

In dependence on the kind of M sites' spatial distribution far-rangingantenna (44) under specified (fixed) elevation angle of observation mayperiodically revolve in azimuth plane to monitor currently (permanently)the adjacent land sky all around the anti-hail protection area of Msites, may periodically rock (scan) within a specified azimuth sector tomonitor currently (permanently) a specified sector of sky of theadjacent land or may uninterrupted observe a specified part (point) ofthe sky of the adjacent land at specified (fixed) azimuth angle ofobservation. Spatial disposition of any teledetection system (43) andthe elevation angle of observation of far-ranging antenna (44) aredefined from the assumption (the condition) that the footprint offar-ranging antenna (44) beam at the altitude of 3.5 km should belocated above (over) the adjacent land located 3-4 km far from thecorresponding edge (boundary) of the anti-hail protection area.

As far-ranging antenna (44) any kind of antenna may be used, e.g. horn,one mirror parabolic and hyperbolic, two mirrors (Cassegrainian)parabolic, dielectric, etc. with any beamwidth. Preferable antennabeamwidth for far-ranging antenna (44) is 10-20⁰ at 3 dB level. Thefar-ranging radiometric receiver (45) of any (each) of K teledetectionsystems (43) may operate at any allowed central radio frequency from Lto W-band of microwave (L, S, C, X, Ku, K, Ka, W), at any interference(noise) free bandwidth of receiving (reception) and at any polarizationof sensing. Preferable bands for operation are X, Ku, K and Ka. Asfar-ranging radiometric receiver (45) any kind of (type) radiometricreceiver may be used, such as a radiometer with a direct amplification,a superheterodyne radiometer, a noise-compensated (direct) radiometer, aDick radiometer, a correlation radiometer, a crystal (detector)radiometer, etc. For far-ranging radiometric receiver (45) preferredintegration time is 1-5 second and preferred sensitivity is 0.1-0.5K independence on frequency band. A preferable azimuth direction for aradiometric observation by teledetection system (43) at (under) fixed(specified) azimuth angle of observation is the sector NorthWest-North-North East, since it will allow practically exclude the Sundirect influence on far-ranging antenna (44) at any time and at anyseason.

Any teledetection system (43) should be mounted or it is necessary tomount any teledetection system (43) under a convex radiolucentprotective apron (shed, canopy, hovel) or/and to cover far rangingantenna (44) by radiolucent protective layer to prevent ice and liquidaccumulation in front of far-ranging antenna (44) and to protectfar-ranging antenna (44) and far-ranging radiometric receiver (45) fromdirect influence of dust and precipitation, e.g. rain, snow, hail, etc.If the protective apron is constructed from a non-transparent orpartially transparent material, then the apron should not cover (cut)the beam (the main lobe) of far ranging antenna (44).

For operating teledetection system (43) with revolving (rotating) orrocking (scanning) far-range antenna (44) it is necessary to take intoaccount sun direct influence and interference.

As far-ranging transmitter (49) any kind of radio waves transmitter maybe used, e.g. cell phone GSM system, etc. with a separate or commonpower supply, that is far-ranging power supply (50).

When any of K teledetection systems (43) detects hail (hail cloud) at aspecified azimuth angle of observation it creates and transmits on theair the alert code-signal on (about) gathering (coming, impending) haildanger from the adjacent land of a specified azimuth direction which isreceived by any of receivers (14) of M detector-warners (7). Received byany receiver (14) the alert code-signal on (about) gathering (coming,impending) hail danger from the adjacent land of a specified azimuthdirection is compared in (by) corresponding controlled code comparator(15) with L proper code-signals of the corresponding site, one of whichis coincided with the alert code-signal on gathering hail danger fromthe corresponding adjacent land are located under a specified azimuthdirection, and if received alert code-signal on gathering hail dangerfrom the adjacent land coincides with one of L proper code-signals ofthe corresponding site then the alert operation mode is set forcorresponding hail preventing sonic generator (2) by (in accordancewith) the above described way.

When for anti-hail protection a teledetection complex is used, then thenumber L may reach up to 7-9.

A transmission of the alert code signal on gathering hail danger fromthe adjacent land of a specified azimuth direction may be performed byradio aids (by radio technical devices), by means of cell phone GSMsystem or by other technical means of communication.

Far-ranging power supply (50) may comprise 12V or 24V DC rechargeablesolar battery with a solar power panel or may use electrical network˜110V or ˜220V as a basic electrical source.

Minimal threshold level of any (each) of K far-ranging teledetectionsystems (43) may be corrected and may be changed individually during itsexploitation by corresponding controlled far-ranging controlledsingle-channel thresholder (47).

Any of K far-ranging teledetection systems (43) is set in its working(operating) mode of operation after clarification of the value of acompensation signal of corresponding far-ranging controlled compensationdevice (46). The value of the compensation signal for any of Kfar-ranging teledetection systems (43) location point (area) is definedexperimentally for each point (area) individually by averaging theresults of measurements of clear sky brightness temperatures (more exactantenna or apparent temperatures) carried out during days and nightsunder (for, at) various ambient (near surface) air temperatures 10-30°C.

An automate exploitation or a self-management (self-controlling) of thewide-ranging anti-hail protection network may be realized as well by amain controlling center (51) as shown in FIG. 9. Main controlling center(51) comprises a main receiver (52) for reception of the alertcode-signal or/and the alert code-signal on gathering hail danger fromthe adjacent land, a processor-analyser (53) for processing and analysisof the alert code-signal or/and the alert code-signal on gathering haildanger from the adjacent land, processor-analyser (53) being inelectrical communication with corresponding main receiver (52), a maintransmitter (54) for retransmission of the alert code-signal or/and thealert code-signal on gathering hail danger from the adjacent land, maintransmitter (54) being in electrical communication with correspondingprocessor-analyser (53), and a main power supply (55), main power supply(55) being in electrical communication with corresponding main receiver(52), with corresponding processor-analyser (53) and with correspondingmain transmitter (54). Reception and retransmission of the alert codesignal on gathering hail danger may be performed by means of cell phoneGSM system, by radio aids (by radio technical devices), by means ofradio communication, by means of telephone communication, or by othertechnical means of communication.

Main controlling center (51) receives transmitted on the air the alertcode-signal or/and the alert code-signal on gathering hail danger fromthe specified adjacent land, processes the received alert code-signalor/and the alert code-signal on gathering hail danger from the specifiedadjacent land and retransmits on the air by radio waves the processedalert code-signal or/and the alert code-signal on gathering hail dangerfrom the specified adjacent land which is received in each (any) site ofthe anti-hail protected area of M sites.

Main controlling center (51) may be located inside or outside of theanti-hail protected area of M sites and may be feed by main power supply(55) or by power supply (6) or by separate power supply (33). If thereis not a possibility to use electrical network ˜110V or ˜220V as a basicelectrical source for main power supply (55) then a preferred embodimentfor main power supply (55) is 12V or 24V DC rechargeable solar batterywith a solar power panel.
